D_IP_PLUGIN_INITIALISE

This page applies to Harlequin v13.1r0 and later; and to Harlequin MultiRIP but not Harlequin Core

D_IP_PLUGIN_INITIALISE Selector

Parameter: PlugInitParam *param

Call type: Single‐call

This is the fourth startup call made to an input plugin. It is used to set up any state required by the plugin as a whole. Unlike the D_INITIALISE selector for output plugins, the plugin should not attempt to access any hardware or install any interrupt drivers, and so on, during this call.

D_IP_PLUGIN_INITIALISE is followed by a call to D_SECURITY .

TEXT

      typedef struct plugInitParam { int32 version ;
      int32 memAllocated ; int32 returnCode ;
    } PlugInitParam ;

Note: By this point, the globalState pointer in the IPPluginContext structure passed to the plugin will have been correctly initialized.

version

The version field should be ignored.

memAllocated

The RIP sets this to indicate the amount of global memory actually allocated in response to the amount requested in the D_IP_BOOT call.

If this is less than the amount requested (usually zero if it is), the plugin may refuse to boot by setting returnCode , below, appropriately.

returnCode

The plugin should set returnCode to CONTINUE_BOOT if the memory allocated is sufficient and the plugin can continue to operate. If not, it should set it to ABORT_BOOT , after which the plugin boot is aborted, and the plugin is ignored.
